If you think of the lower ranks, for example IT admins who ensure that the computers are working smoothly, what's the difference between company A and company B? What do they experience? In most cases they do the same work regardless of which company they are in. The company culture in how people treat each other and how the work is organized in general is what they see. If you have a company with a clear internal structure, a clear product vision and well adjusted workers, then I suppose that work for IT is quite fine. So, I think for 90-99% of the employees it doesn't really matter what the product is. Their work is the same and a well organized company makes it pleasant. So it's not hard to imagine how employees can be happy there. For the higher-ups who make the decision to create and sell products that hurt or kill people I see more of a moral dilemma. But I suppose they are compensated well with money and would have difficulty to find a better job elsewhere. Not sure if they feel the weight when they go to sleep.
